km/h and returns at a speed of 60 km/h. If the distance between the two cities is 240 km, what is the average speed for the entire journey?Solution
Time to travel from A to B = 240 / 80 = 3 hours Time to travel from B to A = 240 / 60 = 4 hours Total distance = 240 + 240 = 480 km Total time = 3 + 4 = 7 hours Average Speed = Total Distance / Total Time = 480 / 7 ≈ 68.57 km/h
